Right now, the Emacs mode preprocesses all input being typed by the user, and if he types ∇ followed by a symbol name, the external function editor is opened and the command is never actually sent to the interpreter. This works fairly well, but there are some annoyances:
- Emacs doesn't know if the typed text is on the command line, or input from ⍞, for example. - There are some buffer state issues in Emacs that is caused by a newline being inserted which messes up the parsing of the prompt. I think a better solution would be if there was a way I could ask GNU APL to not start the internal line-based function editor, and instead reply with some special code (prefixed by a special character perhaps?) that could trigger the opening of the function editor. Another solution could be to control this from the native code plugin. For example a function that I could call to register a callback that is called whenever the ∇fn command is issued. All of the above also applied to the )ED command that I discussed in my previous mail. Regards, Elias
